The wet separation process is positioned after the DRANCO digester in order to treat a digestate free from sticky organic components which are converted into biogas in the digester, facilitating wet separation and optimal removal of inerts and sand. Inerts, sand and organic fraction can be recovered and cleaned in order to produce marketable end-products. This increases landfill diversion, organic diversion and recovery of materials. Organic Waste Systems (OWS) has developed the SORDISEP process for the treatment of municipal solid waste to recover a maximum amount of recyclable components and a high quality compost. The Sordisep process is applied in the DRANCO installation in Bourg-en-Bresse, France, treating 66.000 tons of MSW per year and producing high quality compost according to the standards.
